ZMS is the abreviation of Zephyr Memory Storage. It is a storage developed to target especially the non erasable devices. The new memory storage system inherit from the NVS storage multiple features and introduce new ones : * Inherited features : - light key-value based storage - cache for entries - Wear Leveling of flash memory - Resilience to power failures * New features : - cycle counter for non erasable devices (instead of erase emulation) - Keys up to 32-bit - Built-in support of CRC32 for data - Small size data (<= 8 bytes) integrated within entries Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit d4e246d) (cherry picked from commit d027f10)
List of added tests : - zms.test_delete - zms.test_zms_cache_collission - zms.test_zms_cache_gc - zms.test_zms_cache_hash_quality - zms.test_zms_cache_init - zms.test_zms_corrupted_sector_close_operation - zms.test_zms_corrupted_write - zms.test_zms_full_sector - zms.test_zms_gc - zms.test_zms_gc_3sectors - zms.test_zms_gc_corrupt_ate - zms.test_zms_gc_corrupt_close_ate - zms.test_zms_mount - zms.test_zms_write Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit 004d6d6) (cherry picked from commit fac1b34)
This adds a user application that shows the usage of ZMS The sample app shows three main functions of ZMS: - read/write/delete key/value pairs - fill all storage and delete it - calculate free remaining space Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit fb7dae7) (cherry picked from commit 7584f50)
This adds the documentation for the Zephyr Memory Storage system. Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit 3c4fcaa) (cherry picked from commit 77095d5)
Introduce ZMS_LOOKUP_CACHE_FOR_SETTINGS Kconfig option that enables a dedicated hash function for the ZMS lookup cache that takes advantage of the ZMS ID allocation scheme used by the ZMS settings backend. As such, this option should only be used if an application uses ZMS via the settings layer. Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit 6ccfcdc) (cherry picked from commit 810873e)
This resolves some addressed comments in this PR zephyrproject-rtos/zephyr#77930 It adds as well a section in the documentation about some recommendations to increase ZMS performance. Upstream PR #: 80407 Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit a40ba482bd65ba75540454468cbce4cfcbcc4bf2) (cherry picked from commit 53f2704)
